Perception

RULE

Core Rulebook > Chapter 9: Playing the Game > General Rules > Specific Checks

Perception measures your ability to be aware of your environment. Every creature has Perception, which works with and is limited by a creature’s senses (described on page 464). Whenever you need to attempt a check based on your awareness, you’ll attempt a Perception check. Your Perception uses your Wisdom modifier, so you’ll use the following formula when attempting a Perception check.

Nearly all creatures are at least trained in Perception, so you will almost always add a proficiency bonus to your Perception modifier. You might add a circumstance bonus for advantageous situations or environments, and typically get status bonuses from spells or other magical effects. Items can also grant you a bonus to Perception, typically in a certain situation. For instance, a fine spyglass grants a +1 item bonus to Perception when attempting to see something a long distance away. Circumstance penalties to Perception occur when an environment or situation (such as fog) hampers your senses, while status penalties typically come from conditions, spells, and magic effects that foil the senses. You’ll rarely encounter item penalties or untyped penalties for Perception.

Many abilities are compared to your Perception DC to determine whether they succeed. Your Perception DC is 10 + your total Perception modifier.
